Coarse grain
The grains of a rock are the individual mineral particles that make up the rock's composition. These grains can vary in size, shape, and color, depending on the type of rock and the process by which it was formed. Fine-grained rocks have smaller grains, while coarse-grained rocks have larger grains.
Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.
When all the grains in a rock are large and easy to see, the rock is described as having a coarse texture. This typically indicates that the rock formed from slowly cooling magma deep beneath the Earth's surface.
The grain property of rock fragments refers to the size, shape, and arrangement of mineral grains within the rock. It is important for determining the rock's texture and can provide information about the rock's formation history and the conditions under which it was formed. Grain size can range from fine (tiny grains) to coarse (larger grains), impacting the overall appearance and characteristics of the rock.
When all the grains in a rock are large and small to see, the rock is described as having a bimodal grain size distribution. This means that the rock contains both large and small grains, with little to no medium-sized grains present.
Visible crystals or grains would be referred to as a coarse grained texture.

Granite typically has a coarse-grained texture, meaning that the individual mineral grains are large enough to be seen with the naked eye. The grains in granite are usually interlocking, giving the rock its strong and durable structure.
The size of the grains in a sedimentary rock can be determined by examining the texture of the rock. Coarser grains indicate a larger grain size, while finer grains indicate a smaller grain size. Other features that can provide clues to grain size include the sorting (uniformity of grain sizes) and rounding of the grains.
